Description

Technical Field

[0001] The invention relates to the technical field of building hoisting equipment, in particular to a tower crane hoist suitable for a lightweight partition board and a hoisting method thereof. Background Art

[0002] In the field of prefabricated buildings, the lifting operation of lightweight partition boards currently generally relies on tower cranes and is operated using traditional mechanical hoists. Most of these hoists are rigid clamping structures, such as wire rope binding, bolt clips or simple clamps. However, this clamping method has obvious limitations. Due to the uneven distribution of clamping force, it is easy to cause pressure damage to the surface of the wallboard, and even cause cracks in the internal structure, affecting the overall performance and construction quality of the wall. In addition, in the actual assembly process, a vertical installation method is usually adopted. However, due to the relatively large dead weight of lightweight partition boards, the workers lack effective points of force in their hands during the handling and positioning process, resulting in inconvenient operation and high labor intensity. At the same time, the vertical assembly method is not conducive to the continuous lifting and efficient installation of multiple wall panels. The overall construction efficiency is low, and the convenience and safety of assembly still need to be improved. For this reason, a tower crane hoist suitable for lightweight partition boards and a hoisting method thereof are proposed. Summary of the invention

[0003] The object of the present invention is to provide a tower crane hoist suitable for lightweight partition panels and a hoisting method thereof, so as to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above object, the present invention provides the following technical solution: a tower crane sling suitable for lightweight partition boards, comprising: Fixed beam; A clamping substrate is arranged on the fixed beam; The clamping wing plate is connected to the fixed beam through the adjustment mechanism; And a central controller connected to the adjustment mechanism, which is used to adjust the opening angle between the clamping wing plate and the clamping base plate by driving the adjustment mechanism; in the process of assembling the lightweight partition board, when the lightweight partition board is completed with the clamping base plate, the central controller drives the clamping wing plate to rotate in the direction of the clamping base plate by controlling the adjustment mechanism, so that the angle between the two is gradually reduced.

[0005] As a further solution of the present invention: two hydraulic cylinders are installed at the ends of the clamping base and the clamping wing plate away from the fixed beam, wherein the two hydraulic cylinders connected to the clamping base plate are one group, and the two hydraulic cylinders connected to the clamping wing plate are another group, and the ends of the two groups of hydraulic cylinders away from the clamping base plate and / or the clamping wing plate are provided with flipping mechanisms.

[0006] As a further solution of the present invention: The flipping mechanism includes a bearing beam. Two bearing seats are installed on the end face of the bearing beam adjacent to the hydraulic cylinder. A transmission shaft with ends respectively penetrating through the two bearing seats is arranged between the two bearing seats. The two ends of the transmission shaft are rotatably connected to the ends of the two hydraulic cylinders, and a gearbox connected to the bearing beam is installed at one end of the transmission shaft.

[0007] As a further solution of the present invention: The adjusting mechanism includes a coupling and a control motor arranged on the fixed beam. The output end of the control motor is connected to the coupling, and linkage shafts parallel to the fixed beam are installed on both sides of the coupling that are not adjacent. Rotating shaft supports connected to the end face of the fixed beam are installed at the ends of the two linkage shafts far from the coupling.

[0008] As a further solution of the present invention: The clamping wing plate includes two movable steel plates. The two movable steel plates are respectively connected to the two linkage shafts, and a second reinforcing steel bar is arranged between the two movable steel plates. A pressure sensing structure is installed on the end face of the second reinforcing steel bar adjacent to the clamping substrate.

[0009] As a further solution of the present invention: The pressure sensing structure includes a positioning reinforcing rib plate and a plurality of telescopic units connecting the positioning reinforcing rib plate and the second reinforcing steel bar. A plurality of pressure sensing arrays are arranged on the end face of the positioning reinforcing rib plate far from the telescopic unit. A control unit is installed on the second reinforcing steel bar for controlling the distance between the positioning reinforcing rib plate and the second reinforcing steel bar.

[0010] As a further solution of the present invention: The central controller establishes two-way data connections with the control motor, the gearbox, the control unit, and the hydraulic cylinder respectively through the Bluetooth communication protocol.

[0011] As a further solution of the present invention: A supporting steel beam is also installed on the end face of the fixed beam where the clamping substrate is provided.

[0012] As a further solution of the present invention: The clamping substrate includes two fixed steel plates perpendicular to the end face of the fixed beam and a first reinforcing steel bar connecting the two fixed steel plates.

[0013] A hoisting method for a tower crane spreader suitable for lightweight partition boards includes the following steps: S1. Expand the clamping wing plate to the maximum opening, extend the hydraulic cylinder to the maximum stroke, and at the same time keep the bearing beam in the horizontal loading position; S2. Place the lightweight partition board stably on the clamping substrate, and control the control motor through the central controller to slowly close the clamping wing plate until the pressure sensing structure on the clamping wing plate contacts the side of the lightweight partition board; S3. When the clamping wing plates gradually tend to be in a horizontal state, the control unit controls the telescopic unit to radially extend until the feedback value of the pressure sensing array reaches the preset clamping threshold; meanwhile, the hydraulic cylinder is adjusted to drive the bearing beam to gradually retract until the lower part of the lightweight partition board contacts the bearing plate and is under stable force; S4. Lift the spreader to a predetermined position. The central controller monitors the pressure distribution of the positioning and strengthening rib plates in real time to ensure the stability of the lightweight partition board during the lifting process. After the wallboard is in place, use external supports or temporary fixing devices to stabilize it; S5. After the lightweight partition board is fixed, the central controller sends a flipping instruction to drive the servo motor in the gearbox to drive the transmission shaft to rotate, so that the bearing beam together with the bearing seat connected to the transmission shaft flips to a set angle. At this time, the lightweight partition board disengages from the bearing beam to complete the release. Subsequently, the spreader withdraws from the construction area to complete an operation cycle.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: Through the coordinated cooperation among the clamping substrate, the central controller, the adjusting mechanism and the clamping wing plates, during the assembly of the lightweight partition board, the spreader operates in a horizontal state, thus simplifying the assembly process and improving the assembly efficiency. At the same time, the clamping wing plates and the pressure sensing array work together to realize the adaptive dynamic adjustment of the clamping force, effectively avoiding the surface damage of the lightweight partition board caused by stress concentration and the cracking of the internal structure, and significantly improving the safety and reliability of the hoisting operation.

[0015] Through the wireless coordination mechanism between the central controller and the control motor, the gearbox, the control unit and the hydraulic cylinder, the high-precision synchronization of the clamping and flipping actions is ensured, the accuracy and stability of the installation and positioning of the lightweight partition board are improved, and the potential risks of deviation and falling off during the high-altitude unloading of the board are effectively avoided; at the same time, the modular design and the intelligent control process greatly reduce the manual intervention links, adapt to the industrialized requirements of the rapid installation of wallboards in prefabricated buildings, and the overall construction efficiency is significantly improved compared with the traditional method.

Specific embodiments

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0018] Please refer to Figure 1-7 , in the embodiment of the present invention, a tower crane lifting tool applicable to a lightweight partition board includes: Fixed beam 1; Clamping substrate, arranged on the fixed beam 1; Clamping wing plate, connected to the fixed beam 1 through an adjusting mechanism; And a central controller 16 connected to the adjusting mechanism, which is used to adjust the opening angle between the clamping wing plate and the clamping substrate by driving the adjusting mechanism; during the process of assembling the lightweight partition board, when the lightweight partition board is completed with the assembly of the clamping substrate, the central controller 16 drives the clamping wing plate to tilt and rotate towards the direction of the clamping substrate by controlling the adjusting mechanism, so that the angle between the two gradually decreases.

[0019] Specifically, the fixed beam 1 is a rectangular hollow steel pipe. Two lifting lugs 101 are installed on the end face of the fixed beam 1 away from the clamping substrate, and the two lifting lugs 101 are respectively located on both sides of the fixed beam 1 and are used to connect with the hook of the tower crane, ensuring that the tower crane will not tilt to one side during the hoisting of the light partition board. A supporting steel beam 2 is also installed on the end face of the fixed beam 1 where the clamping substrate is located. An extension part extends from the end face of the supporting steel beam 2 close to the clamping substrate. The extension part and the end face of the supporting steel beam 2 enclose an L-shaped structure. The inside of the L-shaped structure is used to fix the upper part of the light partition board, so that the light partition board can be well positioned during the initial assembly process. And an elastic cushion layer is arranged on the inner side of the L-shaped structure, which can effectively protect the upper part of the light partition board, offset the impact force generated during crimping, and prevent the top surface of the light partition board from being crushed and cracked.

[0020] The clamping substrate and the fixed beam 1 are fixedly connected, and a region for placing the partition board is formed by the combination of the clamping substrate and the L-shaped structure. One side of the light partition board is fixed through this region, so that when assembling the light partition board, a horizontal method can be adopted. At this time, one side of the L-shaped structure can be used as a horizontal plane to support the light partition board, and then the subsequent assembly can be completed. And the efficiency of horizontally assembling the light partition board is higher than that of vertically assembling the light partition board.

[0021] The end of the clamping wing plate is connected to the fixed beam 1 through an adjusting mechanism. Before assembling the light partition board, the central controller 16 can drive the adjusting mechanism to adjust the opening angle of the clamping wing plate, making it open relative to the clamping substrate, which is convenient for the staff to place the light partition board on the static clamping working surface of the clamping substrate. Subsequently, the adjusting mechanism is used again to reduce the angle between the clamping wing plate and the clamping substrate, making the two approach each other, so as to realize the clamping and fixing of the light partition board.

[0022] Through the above technical solution, compared with the traditional vertical assembly method, the present application can adopt a horizontal state to assemble the light partition board, thereby improving the assembly efficiency and having better operation convenience and assembly stability: for the specific operation of assembling the light partition board in the horizontal state, first lay the lifting tool flat, and then the central controller 16 drives the adjusting mechanism to adjust the opening angle between the clamping wing plate and the clamping substrate, so that a larger placement space for the light partition board is formed between it and the clamping substrate, which is convenient for the staff to lift and place the light partition board smoothly into the lifting tool; when the assembly of the light partition board is completed, the adjusting mechanism is used again to reduce the angle between the clamping wing plate and the clamping substrate, making the two approach each other and clamp the light partition board to achieve firm fixation. Subsequently, the entire lifting tool together with the light partition board can be lifted by the tower crane to complete the hoisting operation. Compared with the traditional vertical assembly method of the lifting tool, the horizontal assembly operation is more convenient, which not only improves the assembly efficiency but also enhances the safety and stability of the operation.

[0023] Please refer to Figure 4 , in one embodiment, preferably, two hydraulic cylinders 3 are installed at the ends of the clamping substrate and the clamping wing plate away from the fixed beam 1. Among them, the two hydraulic cylinders 3 connected to the clamping substrate are one group, and the two hydraulic cylinders 3 connected to the clamping wing plate are another group. The ends of the two groups of hydraulic cylinders 3 away from the clamping substrate and / or the clamping wing plate are provided with turning mechanisms. By the two groups of hydraulic cylinders 3, the distances between the clamping substrate and the turning mechanism and / or the clamping wing plate and the turning mechanism can be adjusted respectively, so as to meet the clamping requirements of lightweight partition boards with different heights, make the spreader applicable to the hoisting operations of lightweight partition boards of various specifications, and improve the versatility and flexibility of the equipment.

[0024] Please refer to Figure 4 , in one embodiment, preferably, the turning mechanism includes a bearing beam 4. Two bearing seats 5 are installed on the end face of the bearing beam 4 adjacent to the hydraulic cylinder 3. A transmission shaft 6 with ends respectively penetrating through the two bearing seats 5 is arranged between the two bearing seats 5. The two ends of the transmission shaft 6 are rotatably connected to the ends of the two hydraulic cylinders 3, and a gear box 7 connected to the bearing beam 4 is installed at one end of the transmission shaft 6.

[0025] Specifically, an installation groove for placing a lightweight partition board is formed between the two bearing beams 4 of the two flipping mechanisms. The bearing beam 4 includes an L-shaped plate 401 and a bearing plate 402. A stiffening plate 403 is arranged between the L-shaped plate 401 and the bearing plate 402 to enhance the stability between the L-shaped plate 401 and the bearing plate 402. The bearing plate 402 is arranged on the end face of the L-shaped plate 401 away from the hydraulic cylinder 3. The bearing plate 402 contacts the bottom of the lightweight partition board to provide a supporting effect. Two symmetrically arranged bearing seats 5 are installed on the end face of the L-shaped plate 401 away from the bearing plate 402. A transmission shaft 6 is arranged between the two bearing seats 5. The two ends of the transmission shaft 6 respectively pass through the bearing seats 5 and are fixedly connected thereto. The two ends of the transmission shaft 6 are respectively rotatably connected to the telescopic ends of the two hydraulic cylinders 3. Among them, the gearbox 7 is connected to the end of the hydraulic cylinder 3, and the output end of the gearbox 7 is connected to the transmission shaft 6. An angle feedback system and a servo motor are respectively arranged in the gearbox 7, and both the angle feedback system and the servo motor are connected to the central controller 16. The angle feedback system monitors the flipping angle of the bearing beam 4 and converts its flipping angle into a flipping angle signal and feeds it back to the central controller 16, which controls the clockwise or counterclockwise rotation of the servo motor, thereby realizing closed-loop control (the angle feedback system is a prior art and will not be elaborated here). Among them, the servo motor is fixedly connected to the end of the transmission shaft 6. When the servo motor in the gearbox 7 is turned on, it drives the transmission shaft 6 to rotate, and the transmission shaft 6 drives the bearing seats 5 fixedly connected thereto to rotate synchronously. At this time, the bearing seats 5 can drive the bearing beam 4 to complete a 0-90° flip, facilitating the gradual outward expansion of the L-shaped plate 401 during the flipping process, generating an inclination angle with the contact surface of the lightweight partition board, and using the synergistic effect of gravity and mechanical separation to smoothly separate the lightweight partition board from the lifting appliance, completing damage-free unloading of the board. Each component ensures that the flipping action is synchronous, precise, and without impact through the synergistic mechanism of power transmission, angle control, and structural limit, adapting to the needs of diverse construction scenarios.

[0026] Please refer to Figure 4 In one embodiment, preferably, the adjusting mechanism includes a coupling 10 and a control motor arranged on the fixed beam 1. The output end of the control motor is connected to the coupling 10, and linkage shafts 11 parallel to the fixed beam 1 are installed on both non-adjacent sides of the coupling 10. The ends of the two linkage shafts 11 away from the coupling 10 are both installed with rotating shaft supports 12 connected to the end face of the fixed beam 1.

[0027] Specifically, the coupling 10 and the control motor are both fixedly installed in the middle area of the end face of the fixed beam 1. The two linkage shafts 11 on the coupling 10 are driven by the control motor to rotate in the same direction and at the same speed. The rotating shaft support 12 includes a fixed part 1201 and a rotating part 1202. The fixed part 1201 is fixedly connected to the fixed beam 1, and the fixed part 1201 and the rotating part 1202 are rotatably connected. The rotating part 1202 is fixedly connected to the upper part of the clamping wing plate, and the rotating part 1202 is fixedly connected to the end of the linkage shaft 11. During the rotation of the linkage shaft 11, the rotating part 1202 is driven to rotate synchronously, and the rotating part 1202 drives the clamping wing plate to adjust the inclination angle. In addition, the two fixed parts 1201 are used to limit the displacement of the end of the linkage shaft 11, and at the same time, the two rotating parts 1202 provide support for both ends of the linkage shaft 11 to ensure its stability during rotation and avoid the unbalanced state caused by uneven force.

[0028] Please refer to Figure 4 , in one embodiment, in this embodiment, preferably, the clamping wing plate includes two movable steel plates 13. The two movable steel plates 13 are respectively connected to the two linkage shafts 11, and a second reinforcing steel bar 14 is arranged between the two movable steel plates 13. A pressure sensing structure 15 is installed on the end face of the second reinforcing steel bar 14 adjacent to the clamping substrate. Further, the two movable steel plates 13 are fixedly connected to the two rotating parts 1202 respectively, so as to ensure that the linkage shaft 11 can drive the movable steel plate 13 to rotate synchronously while rotating, realize the angle opening and closing, form a dynamic clamping working surface, and through the pressure sensing structure 15, sense the clamping force of the clamping wing plate on the lightweight partition board to ensure that the lightweight partition board will not fall during the hoisting process.

[0029] Please refer to Figure 4 , in one embodiment, in this embodiment, preferably, the pressure sensing structure 15 includes a positioning reinforcing rib plate 1501 and a plurality of telescopic units 1502 connecting the positioning reinforcing rib plate 1501 and the second reinforcing steel bar 14. The thickness tolerance of the wallboard is compensated by adjusting the telescopic amount to ensure that the clamping surface fits without gaps. A plurality of pressure sensing arrays 1503 are arranged on the end face of the positioning reinforcing rib plate 1501 away from the telescopic unit 1502. A control unit 1504 is installed on the second reinforcing steel bar 14 to control the distance between the positioning reinforcing rib plate 1501 and the second reinforcing steel bar 14. The pressure sensing array 1503 monitors the distribution of the contact pressure with the lightweight partition board in real time and transmits the data to the control unit 1504 to form a closed-loop feedback, dynamically adjust the action of the telescopic unit 1502, and make the clamping force balance and stabilize at the set threshold value, realizing the coordinated operation of adaptive clamping and precise anti-damage control.

[0030] Please refer to Figure 4, in one embodiment, preferably, the central controller 16 establishes bidirectional data connections with the control motor, the gearbox 7, the control unit 1504, and the hydraulic cylinder 3 through the Bluetooth communication protocol. The central controller 16 synchronously coordinates the clamping force and the flipping angle to achieve intelligent hoisting operations with self-balanced clamping force and precise linkage of the flipping angle.

[0031] Please refer to Figure 4 , in one embodiment, preferably, the clamping substrate includes two fixed steel plates 8 perpendicular to the end face of the fixed beam 1 and a first reinforcing steel bar 9 connected to the two fixed steel plates 8. Further, the fixed steel plates 8 are rectangular, the top of the fixed steel plates 8 is rigidly connected to the fixed beam 1, and the first reinforcing steel bar 9 horizontally penetrates the two fixed steel plates 8, significantly improving the structural bending rigidity and suppressing local deformation; the two fixed steel plates 8 and the first reinforcing steel bar 9 together form a static clamping operation surface, providing a stable support reference surface for the lightweight partition board. Its rigid connection characteristics ensure no displacement deviation during the clamping process, realizing the integration of the pre-positioning and basic bearing functions of the lightweight partition board.

[0032] A hoisting method for a tower crane sling applicable to lightweight partition boards includes the following steps: S1. Expand the clamping wing plates to the maximum opening, extend the hydraulic cylinder 3 to the maximum stroke, and at the same time keep the carrying beam 4 in the horizontal loading position; S2. Place the lightweight partition board steadily on the clamping substrate, and control the control motor through the central controller 16 to slowly close the clamping wing plates until the pressure sensing structure 15 on the clamping wing plates contacts the side surface of the lightweight partition board; S3. When the clamping wing plates gradually tend to be in a horizontal state, the control unit 1504 controls the telescopic unit 1502 to radially extend until the feedback value of the pressure sensing array 1503 reaches the preset clamping threshold; at the same time, adjust the hydraulic cylinder 3 to drive the carrying beam 4 to gradually retract until the lower part of the lightweight partition board contacts the bearing plate 402 and is stably stressed; S4. Lift the sling to the predetermined position, and the central controller 16 monitors the pressure distribution of the positioning reinforcing rib plate 1501 in real time to ensure the stability of the lightweight partition board during the lifting process. After the lightweight partition board is in place, use an external support or a temporary fixing device to stabilize it; S5. After the lightweight partition board is fixed, the central controller 16 sends a flipping instruction to drive the servo motor in the gearbox 7 to drive the transmission shaft 6 to rotate, so that the carrying beam 4 together with the bearing seat 5 connected to the transmission shaft 6 flips to the set angle. At this time, the lightweight partition board disengages from the carrying beam 4 and is released. Subsequently, the sling withdraws from the construction area to complete one operation cycle.
